2. Let X be the weights of newborn babies in pounds, and denote m to be its median. For a sample of 14, we have: 5.2 11.8 7.1 14.4 6.3 7.5 11.1 5.5 9.8 12.7 10.5 10.9 8.7 9.2 (a) Give point estimates of 0.25, 0.35, m, π0.75. (b) Find the following confidence intervals and, from Table II in Appendix B, state the associated confidence coefficient: i. (X(1), X(5)), a confidence interval for 0.25. ii. (X(3), X(8)), a confidence interval for π0.35. iii. (X(5), X(10)), a confidence interval for "0.5.
